Tilting weir

Type of weir

A tilting weir or tilting gate is a moveable weir that is used for raising and lowering a head of water by controlling the flow of water to a lower catchment area or drainage basin. Typically the plate or paddle of the tilting weir moves up and down in a narrow duct by titling, pivoting or rotating on its bottom horizontal axis - which opens or closes the tilting weir thus controlling the flow of water out of the higher drainage basin. For example, a reservoir, lake, duct, channel, river, pond, dyke or ditch to a lower-lying area or catchment or drainage basin.
